Non-Extraction Orthodontic Treatment with Sequential Distalization Strategy of Clear Aligner

Orthodontic treatment with clear aligners has become an increasingly common choice because of the growing number of patients that ask for esthetic and comfortable alternatives to conventional fixed appliances. Using clear aligners, anterior crowding with lack of adequate space in the dental arch can be solved by molar distalization, which is common strategy applied in the non-extraction treatment of Class II molar relation, and to resolve crowding. This case report describes orthodontic treatment of two patients with moderate crowding using clear aligners. Molar distalization in the manner of sequential distalization, and arch expansion was accomplished with clear aligner therapy. The patients achieved improved facial profile with favorable occlusion.
